SBE 911plus CTD

SBE 911plus CTD
Request Info
The SBE 911plus CTD is the primary oceanographic research tool used by the world’s leading institutions, providing 24 Hz sampling with an SBE 9plus CTD Unit and SBE 11plus V2 Deck Unit. The 911plus system provides real-time data collection over 10,000 meters of cable

The 911plus is easily integrated with an SBE 32 Carousel Water Sampler for real-time or autonomous auto-fire operations. The 911plus’ pump-controlled, T-C ducted flow minimizes salinity spiking caused by ship heave and allows for slow descent rates without slowing sensor responses, improving dynamic accuracy and resolving small scale structure in the water column.
One Conductivity and one Temperature sensor (fitted with TC Duct and constant-flow pump) are included. An optional second (redundant) pair of T and C sensors and pump can be easily installed.

The 911plus supports numerous auxiliary sensors (dissolved oxygen, pH, turbidity, fluorescence, oil, PAR, nitrates, altimeter, etc.) with eight A/D channels.

SBE 9plus Housing (Depth) Selections — MUST SELECT ONE
09P.1xxxxxx Aluminum housing, 6800 m depth rating 9plus is available for maximum depths of 6800 m (aluminum housing for main housing & T & C sensors) or 10,500 m (titanium housing for main housing & T & C sensors). SBE 5T pump is titanium, regardless of housing option, & is rated for 10,500 m.

 
09P.2xxxxxx Titanium housing, 10,500 m depth rating
SBE 9plus Pressure Sensor Range (Depth Limit) Selections — MUST SELECT ONE
09P.xGxxxxx 0 - 2000 psia (1400 m) pressure sensor Pressure sensor is installed in main housing bottom end cap. Unlike modular T & C sensors, pressure sensor is not field-replaceable / swappable. While highest pressure rating gives you most flexibility in using 9plus, it is at expense of accuracy & resolution. It is advantageous to use lowest range pressure sensor compatible with your intended maximum operating depth, because accuracy & resolution are proportional to pressure sensor's full scale range. For example, comparing 1400 & 4200 m sensors:
  • 1400 m sensor:
    initial accuracy = 0.21 m (= 0.015% * 1400 m),
    resolution = 0.014 m (= 0.001% * 1400 m)
  • 4200 m sensor:
    initial accuracy = 0.63 m (= 0.015% * 4200 m),
    resolution = 0.042 m (= 0.001% * 4200 m)
09P.xHxxxxx 0 - 3000 psia (2000 m) pressure sensor
09P.xIxxxxx 0 - 6000 psia (4200 m) pressure sensor
09P.xJxxxxx 0 - 10,000 psia (6800 m) pressure sensor
09P.xKxxxxx 0 - 15,000 psia (10,500 m) pressure sensor
SBE 9plus Connector Selections — MUST SELECT ONE
09P.xx1xxxx XSG/AG connectors on CTD, T&C sensors, pump, and related cables Wet-pluggable connectors may be mated in wet conditions. Their pins do not need to be dried before mating. By design, water on connector pins is forced out as connector is mated. However, they must not be mated or un-mated while submerged. Wet-pluggable connectors have a non-conducting guide pin to assist pin alignment & require less force to mate, making them easier to mate reliably under dark or cold conditions, compared to XSG/AG connectors. Like XSG/AG connectors, wet-pluggables need proper lubrication & require care during use to avoid trapping water in sockets.

09P.xx2xxxx Wet-pluggable (MCBH) connectors on CTD, T&C sensors, pump, and related cables
SBE 9plus JT4 Connector End Cap Electronics Selections— MUST SELECT ONE
09P.xxx0xxx No electronics installed for JT4 connector, 3-pin dummy connector installed 3-pin connector is installed for JT4, but not connected to any electronics.
09P.xxx1xxx Control module for GO 1015 water sampler, includes interface cables (requires water sampler modem)

300 baud modem for water sampler control (see note) is required to support GO 1015 water sampler. With this selection in 9plus, system provides real-time control for G.O. 1015 Rosette water sampler through 3-pin JT4 connector on 9plus top end cap.

*Note: 300 baud modem in 9plus & 11plus has been standard since 2005. For older instruments, it was optional.
09P.xxx2xxx Serial Data Uplink, 9600 unidirectional RS-232, with 9600 baud sensor communication interface (requires water sampler modem channel, limits cable length to 8,000 m, & makes 9plus incompatible with SBE 17plus Searam & other 911plus CTDs that do NOT have this option) 300 baud modem for water sampler control (see note) is required to support serial data uplink. Serial data is multiplexed into 9plus telemetry stream & de-multiplexed by 11plus, outputting to computer through standard 9600 Baud Uplink connector. System supports use of serial data output instrument & water sampler in same cast.

If 09P.xxx3x (19200 baud sensor communication) selected, continuous transmission rate may not exceed 9600 baud (960 bytes/second). Therefore, serial data output instrument must transmit at 19200 baud in burst mode (transmissions separated by intervals with no data transmission, resulting in average rate of 960 bytes/second).

When 09P.xxx2x or 09P.xxx3x is ordered, JT4 connector on 9plus top end cap is a 4-pin connector.

*Note: 300 baud modem in 9plus & 11plus has been standard since 2005. For older instruments, it was optional.
09P.xxx3xxx Serial Data Uplink, 9600 unidirectional RS-232, with 19200 baud sensor communication interface (requires water sampler modem channel, limits cable length to 8,000 m, & makes 9plus incompatible with SBE 17plus Searam & other 911plus CTDs that do NOT have this option)
09P.xxx4xxx RS-232 serial output interface, installed in place of 1015 interface. 9plus data output duplicates output from SBE 11plus deck unit, except that averaging and alignment must be done in post processing. This is a custom option for AUV integration applications. A PC running Seasave will be able to display and archive CTD data directly from 9plus – no deck unit required. This option is typically desired when an AUV / ROV is logging 9plus data. When this is ordered, 9plus transmits serial data through 3-pin JT4 connector on 9plus top end cap at 19,200 baud, 8 data bits, no parity. Power can also be supplied to 9plus through JT4 connector.
SBE 9plus Pump Control Selections — MUST SELECT ONE
09P.xxxx0xx Pump turn-on controlled by conductivity frequency (turns on 60 seconds after conductivity frequency exceeds hardwired value); may not be suitable for fresh water applications This selection is appropriate for most salt water applications.
09P.xxxx1xx Manual pump control allows user to turn pump on and off by command from Seasave software; typically used for fresh water applications

These selections are typically used for fresh water applications:

  • Manual Pump Control - Pump control commands are sent via Seasave V7 through SBE 11plus Deck Unit's Modem Channel connector, but pump control does not interfere with water sampler operation. Manual pump control is enabled/disabled on Pump Control tab in Seasave V7's Configure Inputs dialog box. Pump is turned on and off from Seasave V7's Real-Time Control menu. Note that you must remember to turn pump on; it will not turn on automatically if this option is installed.
  • Water Contact Pump Control - Pump control is independent of water conductivity. Contact pin is on a special dummy plug that connects to JB6 on 9plus bottom end cap. Modifications to 9plus internal wiring to JB6 for this option prevent use of JB6 for a bottom contact switch. Note that you must inspect contact pin periodically for corrosion; corrosion may prevent pump from turning on.
09P.xxxx2xx Water contact pump control connector allows pump to automatically turn on 60 seconds after contact pin is immersed in water (salt or fresh), and automatically turn off when contact pin is removed from water (prevents use of bottom contact switch); typically used for fresh water applications
SBE 9plus Temperature and Conductivity Sensor Selections — MUST SELECT ONE
09P.xxxxx1x Single T & C sensors, with TC Duct & Pump If you select Dual T & C Sensors, secondary (redundant) sensors can be used to verify data from primary T & C sensors, for applications requiring very high accuracy. Secondary sensors come complete with TC Duct & secondary pump (& all associated plumbing), & mount onto main housing bottom end cap like primary sensors. 9plus is compatible with secondary T & C sensors; secondary sensors can be added to system in field without any modification to 9plus electronics.
 

09P.xxxxx2x includes additional SBE 3plus temperature sensor, SBE 4C conductivity sensor, SBE 5T pump, & associated cabling, TC Duct & plumbing, & mounting. Note that secondary pump is powered via same bulkhead connector as primary pump, via included Y-cable (DN 31522 for XSG connectors, DN 32673 for wet-pluggable connectors).
09P.xxxxx2x Dual T & C sensors, with TC Duct & Pump
SBE 9plus Integration Selections — MUST SELECT ONE
09P.xxxxxx0 Standard cage (vertical plumbing) Includes cage, mounting of 9plus to cage, and plumbing installed for vertical deployment.
09P.xxxxxx1 SBE 32 Carousel Water Sampler extension stand (horizontal plumbing) Includes cage, mounting of 9plus to cage, and plumbing installed for horizontal deployment in SBE 32 Carousel Water Sampler extension stand. Does not include extension stand or hardware to mount 9plus cage to extension stand.
09P.xxxxxx2 SBE 32C Carousel Water Sampler (horizontal plumbing) Includes special cage for horizontal mounting under SBE 32C Compact Carousel Water Sampler, and plumbing installed for horizontal deployment.
09P.xxxxxx3 No cage, no integration Sensors, cables, & plumbing are not integrated, but all parts are provided. This selection may be useful for integration in your own vehicle/platform.
SBE 9plus Auxiliary Sensor Options
9p-6a SBE 43 Dissolved Oxygen sensor (Profiling Configuration), 7000 m (XSG/AG connectors). Cable & mount included. (requires 9P.xx1xx) General Information:
  • 9p-6, -7, & -8 include auxiliary sensor, mount, & straight cable to connect sensor to 9plus bulkhead connector. See auxiliary sensor specification sheets (SBE 43, 18, 27) for sensor descriptions. Auxiliary sensor connector type (XSG/AG or wet-pluggable) must match 9plus connector type.
  • SBE 9plus has 8 differential input A/D channels for auxiliary sensors. Each of 4 auxiliary sensor bulkhead connectors on 9plus end cap can obtain input from up to 2 sensors. If connecting 2 sensors to 1 bulkhead connector, YMOLD (to create a y-cable) applies in addition to 9p-6, -7, & -8 price.
  • Additional sensors not listed here — fluorometers, transmissometers, turbidity meters, PAR sensors, altimeters, etc. from third party manufacturers — are compatible with 9plus. These sensors can be purchased from Sea-Bird & integrated with 9plus at our factory, or you can purchase mount kits & cables from Sea-Bird & perform integration yourself. See Third Party portion of price list.
  • User can change sensors on 9plus in field. However, as noted above, Y-cable is required to connect 2 auxiliary sensors to 1 bulkhead connector on 9plus; each Y-cable is unique to sensors being integrated, so changing sensors may require changing Y-cable. In addition, sensor mechanical mountings may need to be changed to suit selected combination of sensors.

Sensor-Specific Information:

  • SBE 43 — SBE 43 is plumbed between conductivity sensor & pump. SBE 43 is available in 600 m plastic housing or 7000 m titanium housing.
  • SBE 18 & SBE 27 — These sensors are only available with a depth rating to 1200 m.
9p-6b SBE 43 Dissolved Oxygen sensor (Profiling Configuration), 7000 m (Wet-pluggable connectors). Cable & mount included. (requires 9P.xx2xx)
9p-6c SBE 43 Dissolved Oxygen sensor (Profiling Configuration), 600 m plastic housing (XSG/AG connectors). Cable & mount included. (requires 9P.xx1xx)
9p-6d SBE 43 Dissolved Oxygen sensor (Profiling Configuration), 600 m plastic housing (Wet-pluggable connectors). Cable & mount included. (requires 9P.xx2xx)
9p-7a SBE 18 pH sensor, 1200 m (XSG/AG connectors). Cable & mount included. (requires 9P.xx1xx)
9p-7b SBE 18 pH sensor, 1200 m (Wet-pluggable connectors). Cable & mount included. (requires 9P.xx2xx)
9p-8a SBE 27 pH/ORP sensor, 1200 m (XSG/AG connectors). Cable & mount included. (requires 9P.xx1xx)
9p-8a SBE 27 pH/ORP sensor, 1200 m (Wet-pluggable connectors). Cable & mount included. (requires 9P.xx2xx)
YMOLD Extra charge for Y-cable to connect two (2) or more sensors to one (1) auxiliary sensor input bulkhead connector on CTD
9p-9a Bottom Contact Switch module (XSG connector, cable & mount included) (requires 9P.xx1xx) Weight is attached with heavy line to switch. Switch closes when weight removed, setting bit in 9plus data stream. This causes alarm to turn on in 11plus Deck Unit, providing early warning that CTD is nearing ocean floor. Bottom contact switch does not use one of 8 A/D channels, so system can accommodate switch in addition to 8 auxiliary sensors.

Bottom contact switch connector type (XSG or wet-pluggable) must match 9plus connector type.

Note: Since 2007, Sea-Bird uses a female bulkhead connector on 9plus for bottom contact switch, in place of male bulkhead connector. This change was made to differentiate bottom contact switch connector from sea cable connector. See bottom end cap photo above & Application Note 86.
9p-9b Bottom Contact Switch module (Wet-pluggable connector, cable & mount included) (requires 9P.xx2xx)
SBE 9plus Wide Range Calibration Options
9p-12a Wide Range Calibration - Primary T & C (+45 degrees C & 9 S/m) Standard calibration range goes up to +32.5 °C & 6 S/m; more than 99% of oceanographic work is below this temperature & conductivity. Our calibration equations & fits permit extrapolations significantly beyond this range with only minor loss of accuracy. Wide range calibration goes up to +45 °C (additional calibration points at 36, 40, & 45 °C) & 9 S/m. See Application Note 94: Wide-Range Conductivity Calibration.

Wide range calibrations require a 12-week lead time.

Buy Now		 RS-232 serial data uplink cable, DB-9P to DB-9S, 3 m Null modem cable connects computer to Serial Data Uplink on 11plus V2 back panel. See 171890 for pinouts.

300 baud modem for water sampler control (see note below) & Serial Data Uplink selection in 9plus is required to support serial data uplink. Serial data is multiplexed into 9plus telemetry stream & de-multiplexed by 11plus V2, outputting to computer through standard 9600 Baud Uplink connector. System supports use of serial data output instrument & water sampler in same cast.

If 19200 baud serial data uplink selected, continuous transmission rate may not exceed 9600 baud (960 bytes/second). Therefore, serial data output instrument must transmit at 19200 baud in burst mode (transmissions separated by intervals with no data transmission, resulting in average rate of 960 bytes/second).

*Note: 300 baud modem in 9plus & 11plus has been standard since 2005. For older instruments, it was optional.
